## Running ANGLE under GAPID on Android
[GAPID](https://github.com/google/gapid) can be used to capture a trace of the Vulkan or OpenGL ES command stream on Android.
For it to work, ANGLE's libraries must have different names from the system OpenGL libraries.
This is done with the gn arg:
```
angle_libs_suffix = "_ANGLE"
```
All [NativeTest](https://chromium.googlesource.com/chromium/src/+/master/testing/android/native_test/java/src/org/chromium/native_test/NativeTest.java) based tests share the same activity name, `org.chromium.native_test.NativeUnitTestNativeActivity`. Thus, prior to capturing your test trace, the specific test APK must be installed on the device. When you build the test, a test launcher is generated, for example, `./out/Release/bin/run_angle_end2end_tests`. The best way to install the APK is to run this test launcher once.
In GAPID's "Capture Trace" dialog, "Package / Action:" should be
```
android.intent.action.MAIN:org.chromium.native_test/org.chromium.native_test.NativeUnitTestNativeActivity
```
The mandatory [extra intent argument](https://developer.android.com/studio/command-line/adb.html#IntentSpec) for starting the activity is `org.chromium.native_test.NativeTest.StdoutFile`. Without it the test APK crashes. Test filters can be specified via either the `org.chromium.native_test.NativeTest.CommandLineFlags` or the `org.chromium.native_test.NativeTest.Shard` argument.
Example "Intent Arguments:" values in GAPID's "Capture Trace" dialog:
```
-e org.chromium.native_test.NativeTest.StdoutFile /sdcard/chromium_tests_root/out.txt -e org.chromium.native_test.NativeTest.CommandLineFlags "--gtest_filter=*ES2_VULKAN"
```
or
```
-e org.chromium.native_test.NativeTest.StdoutFile /sdcard/chromium_tests_root/out.txt --esal org.chromium.native_test.NativeTest.Shard RendererTest.SimpleOperation/ES2_VULKAN,SimpleOperationTest.DrawWithTexture/ES2_VULKAN
```
